[OpenSER-Users] Openser as a conditional stateless proxy - sr-users

3 Nov 2007

Hi all,

Can any one tell me if the same running instance of Openser can be 
configured as a stateful proxy for some user accounts and for some numbers 
like emergency services, it acts like a stateless proxy, just forwarding the 
request to the destination?

Thanks,
Padmaja
